perf: Fix hist_entry__tui_annotate() build failure
When compiling perf on latest tip/master I see the following
error:
cc1: warnings being treated as errors
util/newt.c: In function 'hist_entry__tui_annotate':
util/newt.c:764: warning: 'ret' is used uninitialized in
this function make: *** [util/newt.o] Error 1
I think the problem was introduced by commit
13f499f076c67675e6e3022973729b5d906a84e9
Below is a patch that fixes the problem.
